These are my pet peeves, most are romance tropes since they're everywhere, lol:
1) The main female protagonist who strongly dislikes the guy for no real reason, only to find out "hey, maybe he's not so bad after all!! O.O" Duh. I can understand if he's kinda a jerk, but if he just bumped into you on your way to lunch??
2) That one nosy friend who can't mind their own business. Usually different for males and females, but equally annoying:
Woman: Usually like the bff from a chic-flick who INSISTS that her friend's life is incomplete without love despite her friend already being independent, employed, healthy and otherwise successful and happy.
Man: The seemingly laid-back friend who warns our plucky protagonist that they should back off from their almost-lover because they "live in different worlds" or "will only cause you pain." Who asked you?!!
3) In action movies when the cool hero and the female lead do those horribly clichéd and unoriginal power games to be "coy." Puns may have worked for James Bond, but now it's just cringeworthy! ><
4) When the world is in danger, and our young protagonist is the ONLY one who can save us. Bonus points if they're born with a weird birthmark or mysterious artifact from dead parent. (Why couldn't the parent save us? O.o)
